Dr. Mollie Leoni, Executive Vice President for Clinical Development of Kura Oncology, discusses the company's ziftomenib program, a menin inhibitor for acute myeloid leukemia (AML). The company initially allowed all AML patients to participate in the clinical study, but later found that specific subtypes, such as those with NPM1 mutation or KMT2A rearrangement, were more likely to respond to the menin inhibitor. They also discovered other subtypes that were responsive, expanding the potential patient population. Understanding the role of menin and menin inhibitors in addressing abnormal gene expression and promoting healthy cell development opens the door to potential combination therapy, where menin inhibitors could be layered onto existing treatments for various cancers related to menin independence.
Mollie explains, "In oncology, we have gotten good at treating the end state, but cancer has many, many causes with a common final endpoint to the way the cells look. So, it's many, many different diseases all at once. We've learned and are learning that with better technology and a better understanding of cancer in general we can identify not just how to stop the end state but how to stop it from starting."
"That's where ziftomenib comes in. Ziftomenib addresses key mutations that when they occur, are what cause the development of cancer. So you're able to shut down the development and force the cells to develop normally rather than waiting until they're already diseased and killing them with chemotherapy or some other cytotoxic agent."
"There is a protein complex that we refer to as the menin MLL complex, which goes rogue when something unusual happens in the cell. For example, that could be an NPM1 mutation. That could be a KMT2A rearrangement. Those are two things that are well-known to happen within AML diseases. It could also be a SETD2 RUNX1 mutation. So many types of mutations could happen that could cause this machinery to go rogue within the cell. And that complex causes genes to become active at levels and at times that are abnormal."
